Some newbie questions
First of all: From what I gathered from
<URL:http://xml.apache.org/mail.html> this is a list for those who
implements the perl wrappers for Xerces. I didn't find any user list,
so I'll try this list.
1) Is there a separate mailinglist for Xerces (Perl) users?
2) Where can I find documentation? I'm quite new to XML and Perl and
need some documentation to manage to write my scripts. There are a
few examples at <URL:http://xml.apache.org/xerces-p/samples.html>,
but they don't contain everything I want to do. I'm also trying to
get help from
<URL:http://xml.apache.org/xerces-c/apiDocs/hierarchy.html>, but
it's not always very intuitive to use the class refrences whithout
mastering Xerces yet. What I need is some more examples. :)
Anyway: The problem I have encountered now is, I guess, a really easy
one. I need to create "<!DOCTYPE adaptor SYSTEM "woadaptor.dtd">" for
the XML document I'm generating. I belive that I have to use
"createDocumentType", but I didn't get it to work. Could someone
please send me the code just to do this?
Thanks in advance.

If they are documented then I'd really like to see them.

Hmmmm. I think I'll go for that solution. It's almost too easy. :)

Ok. I would love if I could move all the Xerces-c docomentation (which
is written using the doxygen system) over to perldoc. That would take
a lot of time. If someone is volunteering to do that, I would be very
grateful, and happy to coordinate the effort.
In the meantime, I'm working on moving xerces-1.5 functionality into
Xerces.pm ...

This is the correct list. The name is a bit confusing, but since
traffic is relatively low, it is fine for both developers and users to
monitor.

I'm sorry to say that Xerces.pm is not very friendly towards beginning
XML users. There isn't any perl specific documentation. The examples
that exist are in the t/ and samples/ sub-directories of the
distribution.
I have my own examples, but they are rather complex, and I don't know
that they would help more than hurt, but I am willing to post them if
need be.

You don't have to use DOM to create documents. You can just use perl's
'print' and write them out a line at a time. Or try using the heredoc
method of printing for printing out big blobs:
print STDOUT <<"XML";
<?xml version="1.0" encoding="iso-8859-1" standalone="no"?>
<!DOCTYPE personnel SYSTEM "personal.dtd">
<!-- @version: -->
<personnel>
</personnel>
XML
That is the simplest method of creating documents.
Now if you really want to create the document in memory using the DOM
API, you can use the following methods:
DOM_DocumentType
DOM_Implementation::createDocumentType (const DOMString &qualifiedName,
const DOMString &publicId,
const DOMString &systemId)
DOM_Implementation::DOM_Document createDocument (const DOMString &namespaceURI,
const DOMString &qualifiedName,
const DOM_DocumentType &doctype)
Here's some output from my thunking around in the debugger:
DB<1> use XML::Xerces
DB<2> $impl = XML::Xerces::DOM_DOMImplementation::getImplementation
DB<3> x $dt= $impl->createDocumentType('adaptor', '', 'woadaptor.dtd')
0 XML::Xerces::DOM_DocumentType=HASH(0x103ec93c)
empty hash
DB<4> x $doc = $impl->createDocument('adaptor', 'foo',$dt)
0 XML::Xerces::DOM_Document=HASH(0x103ecad4)
empty hash
DB<5> x $doc->serialize
0 '<!DOCTYPE adaptor SYSTEM "woadaptor.dtd">
<foo/>
'
Watch out using createDocument(), you will get an Abort (an untrapped
C++ exception) if you don't specify the qualified name, 'foo' in my
example).
Sorry for the delay in answering, I have been ill this week. Let me
know if you need more help.
jas.

This list seems quite I just joined and posted yesterday, no response.
Anyway, I was hoping that once I get it installed it would come with an
adequate set of docs used via the "perldoc" system. Have you looked there
yet?
